sunbmac uses '__u32' for dma handle while invoking kernel DMA APIs, instead of using dma_addr_t. This hasn't caused any 'incompatible pointer type' warning on SPARC because until now dma_addr_t is of type u32. However, recent changes in SPARC ATU (iommu) enables 64bit DMA and therefore dma_addr_t becomes of type u64. This makes 'incompatible pointer type' warnings inevitable. e.g. drivers/net/ethernet/sun/sunbmac.c: In function ‘bigmac_ether_init’: drivers/net/ethernet/sun/sunbmac.c:1166: warning: passing argument 3 of ‘dma_alloc_coherent’ from incompatible pointer type ./include/linux/dma-mapping.h:445: note: expected ‘dma_addr_t *’ but argument is of type ‘__u32 *’ This patch resolves above compiler warning.
